The problem is that a and b may be negative or complex...
If you want a and b to be positive and real, you can use
PowerExpand[(a^b)^(1/b)], but you have to bee sure that you may do it !

The second is undersood as a^(b^(1/b)) and is not equal a !

Dear Colleagues,

why should I not expect MATHEMATICA to (Full)Simplify

(a^b)^(1/b) or a^b^(1/b) to a?

Best regards,
